nubee1974 Posted September 19, 2011 Report Share Posted September 19, 2011 Hi. Just getting back into trials after 20 years out. I've bought a sherco 290 (2000) and am about to do a pre go maintenance job on it. I'm just wondering how much or where you fill the water back up to? Do you just top it right out and let it sort itself out? Also, are they prone to airlocks? Cheers Chris Quote Link to comment Share on other sites More sharing options...

It is crammed in there with the electrics and stuff and hard to get to, still. Usually takes a screwdriver to tap it counter then push it round a couple turns to get it off and out of the way. Need a long skinny funnel to get fluid back in, or make one using a wax paper cone. I think a 50/50 mix of green etheline glycol(green) and distilled water is sufficient, or you can buy the premixed stuff at cycle shops. Hard to see in there without a mirror, but you need to fill it to cover the rad cores and a little over allowing some expansion space. Most just top them off, then let them expell the excess when they warm up, but if you have a cheap syringe with a rubber host and can draw out 10ml-15 or so to give it some headspace for expansion, this is best. Maybe a pint or so is all it takes. Then fumble about with some long marrow pliars or something to hold the cap in line while pushing it round with ehe bloody screwdriver till tight and a tap for securement. No probs with trapped air that I have seen. So Bob is yer mothers brother! Edited September 20, 2011 by copemech Quote Link to comment Share on other sites More sharing options...
